Redis Persistence on Azure not working

Question

Hello.

Please consider this Bicep template:

param deploymentName string = ''

resource storageAccountsRedis 'Microsoft.Storage/storageAccounts@2021-04-01' = {
  name: '${deploymentName}redis'
  location: resourceGroup().location
  sku: {
    name: 'Standard_GRS'
  }
  kind: 'BlobStorage'
  properties: {
    accessTier: 'Cool'
    allowSharedKeyAccess: true
  }
}

resource redisDatabase 'Microsoft.Cache/redis@2020-12-01' = {
  dependsOn: [
    storageAccountsRedis
  ]
  name: '${deploymentName}Redis'
  location: resourceGroup().location
  properties: {
    enableNonSslPort: true
    redisConfiguration: {
      'rdb-backup-enabled': 'true'
      'rdb-backup-frequency': '15'
      'rdb-backup-max-snapshot-count': '1'
      'rdb-storage-connection-string': 'DefaultEndpointsProtocol=https;BlobEndpoint=https://${storageAccountsRedis.name}.blob.${environment().suffixes.storage};AccountName=${storageAccountsRedis.name};AccountKey=${storageAccountsRedis.listKeys().keys[0].value}'
    }
    redisVersion: '6'
    sku: {
      capacity: 1
      family: 'P'
      name: 'Premium'
    }
  }
}

This is a very simple template that deploys Redis, with a backup to Storage Account every 15 minutes. When I deploy it a container -persistence is created in the Storage Account, but no backups ever appear in it. I can't find any errors/warnings regarding backups.

I don't know how should I proceed from here.

Hi, @Michał Borkowski Welcome to the Microsoft Q&A Platform, and thanks for your query.
As we understand you are trying to deploy a sample template to Redis and you are facing an issue as -persistence is created in the storage account.
By seeing the code which you have shared is not supported, The Redis cache persist file is "Page blob" The account type "BlobStorage" does not support page blob.
Change it to StorageV2 and give it a try.
